Starting from point O, a person walks towards west facing 4 km and reaches point A. From there, he walks 4 km to the right and reaches point B, then he walks 4 km to the right and reaches point C. After that, he again turns right and walks 3 km to reach point D. Now he walks 4 km to the left and reaches point E. Then he turns right and walks 5 km and reaches F. The minimum distance (in km) between point A and point E is:
1
\(5\sqrt 65\)
2
\(\sqrt 68\)
3
\(\sqrt 65\)
4
\(2\sqrt 65\)
